- Tripled Google Stake: The firm’s Alphabet holdings surged to approximately 58 million shares, up from under 20 million shares previously, indicating a strong conviction in the tech giant’s long-term prospects.
- Portfolio Consolidation: By trimming 16 positions entirely, Abel appears to be focusing on fewer, larger bets — a strategy that reduces diversification but increases conviction weighting.
- Sector Rotation Implications: The exits from payments (Visa, Mastercard) and e-commerce (Amazon) may suggest a shift away from consumer discretionary and financial technology sectors toward more capital-light, cash-flow-rich tech platforms.
- Timing and Context: The moves occurred in the first quarter of 2026, a period of mixed market sentiment amid interest rate uncertainty and regulatory scrutiny of big tech. The timing may reflect Abel’s desire to act swiftly rather than wait for a more stable environment.

Key Highlights
Greg Abel, who recently succeeded Warren Buffett as Berkshire Hathaway’s chief executive, oversaw a significant portfolio restructuring during his initial quarter in charge. According to the latest regulatory filings, the firm completely sold out of its holdings in Visa, Mastercard, Amazon, and UnitedHealth Group — names that had long been core positions under Buffett’s tenure.
At the same time, Berkshire boosted its Alphabet (Google) stake by approximately threefold, bringing the total to around 58 million shares. This aggressive accumulation makes Alphabet one of Berkshire’s top holdings. The moves suggest Abel is steering the portfolio toward technology and away from traditional consumer finance and healthcare names.
The filings did not specify whether the sales were driven by valuation concerns, sector rotation, or a desire to simplify the portfolio. Berkshire’s 13F filing, which provides a snapshot of U.S.-listed equity holdings as of the end of the quarter, revealed 16 complete exits and several new additions in other sectors.
No recent earnings data was cited in connection with these trades; rather, the activity reflects the new CEO’s early approach to capital allocation. Abel has long been involved in Berkshire’s non-insurance operations, and his first quarter as CEO offers the clearest signal yet of his investment philosophy.

Expert Insights
The early actions of a new CEO at a firm like Berkshire always draw intense scrutiny, and Abel’s portfolio reshuffle offers several professional takeaways. The decision to triple Alphabet while exiting names like Visa and Mastercard suggests a bet on advertising-driven digital ecosystems over transaction-based models. Alphabet’s cash generation and dominance in search and cloud could be seen as more predictable in a high-rate environment compared to consumer credit-sensitive firms.
Conversely, the complete sale of Amazon — a company that underperformed broad tech in 2025 — may indicate concerns about its retail margin trajectory or capital expenditure requirements. Similarly, exiting UnitedHealth in a healthcare sector facing policy headwinds could reflect a cautious stance on regulatory risk. The sale of Visa and Mastercard, both perennial Buffett favorites, is perhaps the most symbolic: it may signal a generational shift away from financials toward tech.
Investors observing Berkshire’s filings often interpret them as a potential roadmap for value-oriented allocation. However, given Berkshire’s unique scale and long-term horizon, these moves may not be directly replicable for individual portfolios. The ultimate success of Abel’s first-quarter transactions will likely depend on whether Alphabet can maintain its growth momentum and whether the exited stocks underperform relative to their replacements. For now, the portfolio shift points to a CEO willing to move decisively — a trait that may comfort or concern Berkshire’s long-term shareholders.
